SHADE-FIXTURE.

Specification of Letters Patent.

Patented Sept. 16, 1913.

Application filed April 1, 1913. Serial No. 758,153.

'isa vertical sectional view looking at the inside of one of the brackets; and Figs. 4 and 5 are detail views of modified forms of the locking device.

The obj ectof this invention is to provide simple means whereby the shade may be raised and lowered without the use of springs in the rollers, these springs being objectionable because of the expense of manufacture, the tendency to get out of order and for other reasons.

In the drawing, a designates the shade roller and b the shade attached to and wound thereon in the usual manner. Fastened to the ends of the shade roller are the pintles c which are rotatably journaled in brackets (Z fastened to the window frame. One of the journals 0, at a point between the bracket and the adjacent end of the shade roller is made angular in cross section, at e. Pivoted on the adjacent bracket (Z is a locking lever f which is provided at its forward end with an angular notch g which normally tends to engage the angular part e and to thereby lock the shade roller against rotation.

To cause the normally locking tendency of the lever f I may provide the rear end thereof with a weight k or I may employ a leaf-spring h, as shown in Fig. a or a retractile coil spring 71 as shown in Fig. 3. An operating cord 2' has one end wound around the shade roller at one end thereof, thence the cord is carried backwardly and passed through an eye 3' fastened to the bracket, thence through an eye is fastened to the weighted end of the lock lever, thence through an eye Z' fastened to the forward ,part of the bracket, at a point above the eye 0, and from this last named eye Z the cord depends to a point within convenient reach of a person standing on the floor near the window.

Before the shade is mounted in the brackets, the shade fabric is completely wound upon the roller and the cord is unwound, so that the shade will be at its highest point and the cord will depend to its lowest point. To lower'the shade, the operator takes hold of the shade stick with one hand and the cord with his other hand; then by drawing the cord taut the lock lever will release th shade roller and hold it released while the operator with his other hand draws down the shade fabric, paying out the cord with his other hand as the cord is wound upon the roller but at all times holding the cord taut enough to prevent the lock lever engagin the shade journal a. To

raise the shace it is simply necessary to pull downwardly on the cord, which action holds the lock lever out of locking engagement and unwinds the cord from the roller and thus winds the shade fabric upon the roller. The shade may be locked at any point by simply releasing or easing up on the cord.

It will be observed that it is essential that the cord shall be wound upon the roller in a direction reverse to the winding of the shade fabric thereon. It will also be observed that if desirable the cord may be wound upon a small wheel or drum formed on or attached to the shade roller instead of directly on the shade roller.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

In combination, window brackets, a shade roller journaled to rotate therein, a normally acting locking device for locking the shade roller against rotation, a cord having one end wound upon the shade roller in a direction reversed to the winding of the shade fabric thereon, and means whereby when the cord is drawn taut the locking device will be held out of action and thus free the shade roller so that the same may be rotated by the shade in one direction and by 'means of the 00rd in the opposite direction In testimony whereof I hereunto afiix my said means consisting of three eyes, one on slgnatul'e in the presence of two wltnesses. the locking device and one at the front end of the bmeket and the remaining one at the CHAS MONCURE 5 rear end of the bracket, the said cord being Vitnesses:
